UNITED STATES PATENT OFFI ICE-HOUSE PLOW.

Application filed April 16, 1925. Serial No. 23,648.

My invention relates to power ice cutters and more particularly to thetype designed for use within ice houses, in preparing previously storedice for sale or loading on delivery trucks, 7

The objects of my invention are to provide a light weight, simple andinexpensive construction, yet efiicient means for the economicalhandling and cutting of ice during the process of delivery from thestorage house; to eliminate ice house hand plowing and hand chiseling;to provide a machine of so called one man control designed and arrangedto center the control at the operating position; to provide a novelhoist fall adapt-able to hold aloft the cutting saw while out ofoperation; and to provide the various other advantages and results madeevident in the following specification.

.My device is particularly adaptable for operation by an electric motorbut it is evident that any suitable driving force may be used. For houseplow purposes light weight is extremely desirable and my con structionis designed to meet this requirement.

Referring to the accompanying drawings, which form a part of thisspecification, Figure 1 shows a side View of my device. Figure 2 shows afront view thereof. Figure 3 shows the detail of my hoist fall.Referring again to Figures 1 and 2, T shows the sled runners on which mydevice rests, B shows the cross pieces of the sled.

C shows the standards in which the ends of the rod A are secured. Thestandards are mounted on the cross piece which connects the runnersintermediate their respective ends and, as shown, are spaced inwardlyfrom the runners. F shows the rocking beams consisting of angle ironshaving vertical flanges pivotally mounted on the rod A, on the end ofwhich beams F is carried a circular saw G, the saw shaft turning in thejournal blocks B. Q shows the cross pieces which join the rocking beamsand which are supported on the inwardly disposed horizontal flanges ofthe beams and on opposite sides of rod A to form a platform to which themotor H is bolted. D shows depth gage uprights mounted on the runners Tand between the pivot or rod A and the saw G at the forward end of theframe. E shows openings in the uprights through appropriate pairs ofwhich a rod is placed to regulate the drop of the rocking beams F. Ishows the switch box, U shows the electric cord, K shows the chaintransmitting power from the motor H to the saw. L shows the chain guard,S shows the saw guard, J shows the operating handles formed rearwardlyof the motor. by the upwardly inclined portions of the beam whichinclined portions are joined at their respective outer ends by the braceV. Referring again to Figure 3, M shows the hoist fall, N shows the slotin the fall, 0 shows the pin on which the fall locks, P shows the tripstring which releases the hoist fall from its locking position.

Similar letters of reference refer to similar parts throughout thevarious views.

To operate, the depth gage is set at a point to regulate the desired cutof the saw. The operator then takes his place at the handles J, slidesthe plow to the cutting position,'switches on the current, pulls thetrip string P, releasing the hoist fall, whereupon the rotating sawdrops to the cutting position, and the plow is pushed about by thehandles until such time as the desired cut is obtained. Instant controlover the cutting is had by pressing down the handles J thus elevatingthe saw away from the cutting surface. The hoist fall locks the saw inits raised position until the string P is again tripped. For quick workthe power is seldom shut ofi', the operation being controlled entirelyfrom the handles. The simplicity of my device renders it particularlyfree from technical repair requirements, and its use fills a long feltwant in indoor handling and cutting of ice.

I do not desire to confine myself to the specific details ofconstruction herein set forth and described, but claim suchmodifications and equivalents as may be construed within the scope ofthe appended claim.

Having thus described my invention I claim as new and desire to secureby Letters Patent of the United States of America An ice house plowincluding a pair of spaced runners, a cross beam connecting the runnersintermediate their respective ends, standards mounted on the cross beamand centered between said runners, a pair of.

spaced parallel angle beams extending longitudinally between thestandards with their forward ends in advance of the runners and theirrear ends disposed upwardly at an inclination to the horizontal, each ofsaid angle beams presenting a vertical side flange disposed against theinner face of an adjacent standard and a horizontal bot tom flangeextending invvardlyat right an: gle to the standard, a transverse pivotrod having its ends supported in said standards, said rod extendingthrough the said side flanges of the angle beams at pointssubstantiallyintermediate the ends of the said beanis, a pair of cross pieces joiningthe angle beams on respectively opposite sides of the pivot rod andsupported on the said bottom flanges of the angle beams, said crosspieces being equidistantfrom the pivot rod, a motor supported on thecross pieces and centered over the pivot rod, a handle brace connectingthe upwardly disposed rear ends of the angle beams, a saw centeredbetween the forward ends of the angle beams, and driving connection fromthe said motor to the said saw.

In testimony whereof I afl-ix signature. Y
